Re: The big thud
I definately get different sensations... sometimes it is barely noticeable and other times it is impossible to ignore, sometimes it will just be one or two but sometimes it's several in a row or a few seconds apart. It usually doesn't really worry me to the point of anxiety because it's just something I've had as long as I can remember, but once in a while it will just seem 'worse' than 'normal' for some reason and that will make me worry a bit, which of course does nothing except make the whole issue worse. If you've been thoroughly tested then the lightheadedness and sweaty palms, etc. probably have more to do with your anxiety than the PVCs directly. You said you had trouble seperating the symptoms but keep in mind that they're kind of inter-related in that anxiety can increase the sensations which in turn can increase anxiety.
